Jomisinonzrnnog or i lo a llio h om it may concern makeand usethefsame. This invention relates to self-threading shuttles of. the. type employed in automatic I vThe invention Be it-fknown that I, Jonas Nonrrmor, a. citizen of; the United States, residing at Hopedale, in the county of Worcester and State of Massachusetts, have invented certain new and useful "Improvements in Shut-- tles'; andI do hereby declare the following. to be a full, clear, and exact description of the invention, such as; will enable others skilled in the art'to which it appertains to weft-replenishing looms. I

Inshuttles. of the type in question it is common to employ a threading-device having means by which the threadis auto-- matically directed into a longitudinal I thread-passage near. the endof the shuttle, and from thence through an eye in the forthrea d makes an angle, so that a guidingdevice of some sort is necessarily provided,

around whichj'the thread is drawn and'deflected at this point; This thread-guideis. subjectedto-wear, owing to the friction of the thread against it,- andit is therefore common to employ wear-resistant material, such as porcelainor glass, in the construction of the "thread-guide; 1

improve and simplify the means by which I 'awear resistant thread-guide is provided at the point above indicated, and'to this end the; invention consists in the construction hereinafter described, as-it is defined in the appended claim- I I In the accompanying drawings-Figuresl' and2 'are, respectively, a plan-view and a front-elevation of the forward portion 'of ashuttle embodying the present invention,

and Figsg' 3, 4' and -5' are, respectively, a

The thread-guiding device inwhiehthe present invention resides is employed at this I point. F or this purpose the threadin'gdevice is provided with an interg'ral doiim 'wardly projecting portion 14,'which' is lo- /cated at the forward extremity of one of,
